*Areej M. Alghoul, Bayan Kh. Al-Qataisheh and Abeer R. Abdelhalim
ABSTRACT
Herb drying is a common preserving technique. However, it may affect the quality of herb, such as changes in the amount of essential oil in herbs as well as the possibility of the formation of new volatile compounds. Scolymus hispanicus is one of the most used wild vegetables in Jordan and has been considered as an important natural source of antioxidants. Essential oils of the fresh and air-dried flowering aerial parts of Scolymus hispanicus L were obtained by traditional hydrodistillation. The chemical constituents of essential oil were analyzed by gas chromatography–mass spectrometry technique (GC/MS). The analysis shows that the essential oil of the fresh sample of Scolymus hispanicus consisted of 47 chemical components, while the dried sample revealed the presence of only 32 components. The Keywords: Essential oils, GC/MS, hydrodistillation, Scolymus hispanicu volatile compounds. [Download Article] [Download Certifiate] |
